AKTIEN- GESELLSCHAFT, or KIEL, GERMANY, A CORPORATION or GERMANY CONTRIVANCE FOR STOWING CARGO ON SHIPS Application filed June 16, 1927, Serial No. 193,389, and in Germany May l'i, 1926.

The invention. concerns a contrivance for stowing cargo on ships, particularly such goods as can only be stowed inone layer, e. g. fruit, cattle or similar. cargoes. In order to be able to utilize the full cargo space for such goods, the height of the hold must be similar to the height of the goods. By building intermediate decks one could so fit up a ship that it correspondsto this requirement.

. cult and such a contrivance can be installed without great cost and without appreciable loss of cargo space.

In the drawing a constructional form of the invention is shown by way of example.

Figure 1 shows a transverse cross section through a part of the hold of a ship fitted up according to the invention, and Fig. 2 shows a longitudinal section. Fig. 3 shows some of the intermediate deck portions in plan view. Figs. 4 and 5' show 1n plan view their height. Moreover one can so adjust the individual portions of the intermediate decks to positions of different height that; goods of difierent height can be stored with the best utilizationof the space on an intermediate deck. Such a disposition of the intermediate deck is shown in Fig. 1. :Goods of smaller size can thereby be stored in the middle of the ship and goods of large size in the outer parts of the cargo hold. The deck portions can also be'adjustcd at various heights in the longitudinal direction, as isevident from Fig. 2.

It ships fitted up according to the'invention are to carry goods for which intermediate decks are not necessary, the individual portions of the intermediate decks are released from the supports and advantageously stored one above the other on the double bottoinof the ship, whereby they simultaneously tor-iii ballast.

A particularly advantageous arrangement tor securing the intermediate deck portions is shown in Figs. 4: and 5. In this the deck gage with their claws Z (Fig. on these angle pieces the deck portions hang by means of screws 6..

If the intermediate decks are to be adjusted for goods of certain dimensions in height, the

individual deck portionsare brought to the corresponding height by means of st-rops 7* and running hooks, and then the claws (Z are put in the holes 72 of the deck supports. The height of the several deck portions can thereupon be still further altered to a slight extent. by turning the nuts and lock nuts 6 of the screws 6 to the left or right. Thisrenders possible a fine adjustment of the deck portions as regards height.

In this way, by simple means, the intermediate decks can be so adjusted for any size of the cargo goods that the hold can be'utilized to the full. V

With the constructional form of the invention shown by way of example in the drawing several intermediate decks are provided.

With this the upper intermediate deck por- 1 tions are provided with apertures for passing through the hoisting slings. The invention may however also be used when there is only one intermediate deck.

I claim:

1. A ship having a fixed deck, a tween deck beneath said fixed deck said tween deck being composed of a plurality of individual plane deck portions, a plurality of upright supports each of said plane tween deck portions being movable in height independently of the other tween deck portions and without connection with said supports, and releasable means for securing said tween deck portions to said supports in positions of difierent height.

2. A ship having a fixed deck, a tween deck beneath said fixed deck, said tween deck being composed of a plurality of individual plane deck portions, a. plurality of upright supports, each ct said plane tween deck portions beii movable in height independently of the other twee=;1 deck portions and Without connection with said supports, and releasable and Z1 ljllSt1blO'1I]8llDS for securing said plane tween deck portions to said supports in positions of diii'erent height.

3. A. shin having a plurality of individual 5 deck portions, each such portion being adjustable in height independently of the other deck 'iortions, means for adjusting said individual deck portions, means for fixing the same when adjusted, and means for varying said adj ustment aitcr fixing the deck portions. 7
